Thanks, Enrique. Q1 was a very strong earnings quarter. We once again grew revenue in constant currency, non-GAAP operating profit dollars faster than revenue and non-GAAP EPS even faster. We are off to a strong start with free cash flow, and overall, we are very pleased with our results.
Now let's look at the details of the quarter. Net revenue was $14.6 billion, down 1% year-on-year or up 1% in constant currency. Regionally, in constant currency, APJ grew 4%, EMEA was flat and Americas declined 1%. Gross margin was 19.6%, up 180 basis points year-on-year, driven primarily by disciplined execution and improved rate in Personal Systems as well as improved Print hardware gross margins.
Non-GAAP operating expenses were $1.7 billion, down $104 million sequentially, resulting from significant reductions in SG&A driven by actions taken through our transformation program. Non-GAAP net OI&E expense was $44 million for the quarter. We delivered very strong non-GAAP diluted net earnings per share of $0.65, up $0.13 or 25% year-on-year, with a diluted share count of approximately 1.5 billion shares.
Non-GAAP diluted net earnings per share exclude net charges totaling $278 million related to amortization of intangible assets, restructuring and other and nonoperating retirement-related credits and other tax adjustments. As a result, Q1 GAAP diluted earnings per share was $0.46.
At the segment level, in Personal Systems, it was a very strong quarter. Revenue was $9.9 billion, up 2% or 4% in constant currency. By customer segment, commercial revenue was up 7% and consumer revenue was down 7%. By product category, revenue was up 6% for workstations, up 2% for desktops and 1% for notebooks. The team continued to successfully manage our overall product mix as commercial demand remains solid while navigating the CPU supply constraints.
Personal Systems has been consistently delivering profitable growth, share gains and improved mix over time. This, combined with disciplined pricing and supply chain favorability, drove exceptionally strong profitability with operating margins of 6.7% and operating profit dollars up 61% year-on-year to $662 million. Personal Systems OP represented 47% of HP's profit mix for the quarter.
In Print, we continue to make progress on our key initiatives, including growing our contractual offerings, gradually shifting more system profitability to hardware and managing supplies, all within a softer print market context. Looking at the details. Q1 total Print revenue was $4.7 billion, down 7% nominally and 6% in constant currency. Print operating margins were 16%, up 40 basis points sequentially, driven by higher gross margins and reduced OpEx, partially offset by a lower supplies mix.
Commercial hardware revenue was down 1% and consumer hardware revenue was down 13%. Total hardware units were down 10%, with commercial units down 12% and consumer units down 10%. The decline in units was driven by market softness, fewer sprocket units, along with our ongoing strategy to focus on more profitable customers.
First quarter supplies revenue was $3 billion, down 7% in constant currency and in line with our expectations. We are executing against both the operational and strategic plans laid out in prior quarters. Overall, Tier 1 channel inventory levels remained below the ceilings.
Let me now turn to our transformation efforts and specifically our cost savings opportunities. In Q1, about 800 people exited the company globally as part of the restructuring activities announced in October 2019. We continue to pursue additional cost savings opportunities in addition to our ongoing productivity efforts. We now have line of sight to $1.2 billion of gross structural cost savings that help mitigate headwinds, create investment capacity and drop significant profits to the bottom line. We will discuss our expected $650 million net OP flow-through in FY '22 later in this call.
Turning to cash flow and capital allocation. Q1 cash flow from operations and free cash flow were very strong at $1.3 billion and $1.1 billion, respectively. This gives us confidence that for the full year, we will land free cash flow between $3 billion and $3.5 billion, even with the short-term negative working capital impact from the coronavirus. In Q1, the cash conversion cycle was minus 30 days. Sequentially, the cash conversion cycle is down 1 day. We returned $691 million to shareholders through share repurchases and $256 million via cash dividends in Q1.
Looking ahead to Q2 and FY '20, keep the following in mind related to our overall financial outlook. We expect that macroeconomic conditions will remain dynamic as they are today, and we expect our end markets to remain competitive. We're expecting currency to have about a 1% year-over-year negative impact. With regards to the financial impact from the coronavirus, we are factoring in our best assumptions at this time, recognizing that the situation remains highly dynamic.
In Q2, we expect a negative impact to our top line, bottom line and free cash flow, although we view the impact as temporary with limited impact to our second half. In total, net of mitigations, we have factored in an $0.08 EPS impact into our Q2 guidance. We are also expecting to have a significant impact to free cash flow in Q2, with negative impacts to working capital due to delayed production and manufacturing timing and back-end loaded revenue linearity. Again, this should be temporary and not materially impact the full year.
Turning to specific Personal Systems assumptions. We expect industry-wide CPU supply constraints to continue to persist, and we expect the cost from the overall basket of components to be less favorable compared to Q1 levels.
In Printing, we're assuming a year-over-year unit market decline, and consistent with our strategy, we will remain focused on profitable customers. We expect operating margins to improve in the second half of the year versus the first half as cost actions are more fully realized.
In addition, for the full year, we expect our non-GAAP tax rate, which is based on our long-term non-GAAP financial projection, to be 16% in FY '20.
Our FY '20 outlook assumes return of capital of at least 75% of free cash flow to shareholders, consistent with our SAM messaging. However, we will talk later about our incremental return of capital plans, which would create upside in FY '20 and are not yet factored into our guidance. Taking these considerations into account, we are providing the following outlook. We are raising our full year fiscal 2020 non-GAAP diluted net earnings per share to be in the range of $2.33 to $2.43 and our full year fiscal '20 GAAP diluted net earnings per share to be in the range of $2.03 to $2.13. We expect Q2 '20 non-GAAP diluted net earnings per share to be in the range of $0.49 to $0.53, inclusive of our best estimates of coronavirus, and Q2 '20 GAAP diluted net earnings per share to be in the range of $0.46 to $0.50.
And now I would like to hand it back to Enrique to discuss our value plan.
